I don’t know why we’re still hearing about this. The narrative is that the Romney campaign was shocked – SHOCKED – to find out that they had lost. TPM amusingly referred to the meme immediately after the election as SHELLSHOCK!
The truth is 1) they believed their own bullshit about Romney momentum, 2) the consultant class of the GOP apparatus needed to portray a winnable race throughout the campaign to ensure a stream of campaigns from the billionaires aided and abetted by 3) a media that needs the excitement of horserace politics to keep the ratings up, the 4) bubble that exists on bullshit mountain kept the campaign (as well as pundits and the rank-and-file) from ever considering anything resembling reality and 5) the electorate is more center-proper or center-left and we are not a center-right nation, or at the very least has been pushed leftward by the Great Recession.
As someone said – the GOP was smoking what they were selling (previously), to disastrous electoral results.
